IMPROVEMENT m norme-MACHINES.

The Sehedue referred. to ln these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, ARTHUR Y. HUBBELL, of Elmira, inthe county of Ohemung and in the State of New York, have invented certain new and usefullmprovements in Flutiiig-liachines; and do hereby des clare that the following is a full, clear, and exact description thereof, reference being had tothe accompanying drawing and to the letters of reference marked thereon making a part of this specification.

The nature of lnyinvention consists of the construction and arrangement of an improved Fluting- Machine,.as will be hereinafter fully set forth.

In order to enable others skilled in the art to which ymy invention appertains to make'and use the same, I

will now proceed to describe its construction and operation, referring to the annexed drawing, inwhichl Figure l is a front view of my h1ting-machine,`part in section;

Figure 2 is an enlarged vertical section of the hub through which the operating-shaft works; and

Figure 3 is a horizontal section ofgthe opera-tingshaft just above the hub. f'

A represents the bedof my machine, upon which are two standards, B and C. lhe standard C rises vertically from the base, and is turned at a right angle so as to be parallel with the base to support the frame for the upper roll, as shown inl; while the other, B, is straight; and in said standards the lower roller D has its bearings. f

Above the point in the standard C where said lower roller has one of its bearings, said standard is slotted vertically for the projecting journal of the upper roller.

E to move in when said roller is moved upv or down.

This upper roller E has its journal-bearings in a frame, G,the inner end of`which is extended downward and moves in a guiding recess in the inner face of the angular standard C, the lower end of said frame reaching into a slot-or mortise in the bed-plate A. That portion of the frame G which moves in the groovod standard C is slotted, so that the journal of the lower roller D may pass through the same; and this slot being elongated allows of the frame moving upaud'down without in anyway interfering with the lower roller.

The object of extending the frame G is that there by a perfectly vertical movement of the frame is insurcd, the frame being kept steady so that the upper roller will at all ytimes beheld parallel with the lower roller. Y'

'Ou the upper side of the horizontal portion of the frame G are two'pins, a a, which pass upward through holes in the horizontal portion of the angular standard C, and act as guides for further. holding the frame G steady and prevent it from vibrating.

Between the guide-pins a a, a suitable distance above the frame G, is placed a spring, H,.which has 'its bearings at either end upon shoulders or osets formed on the pins, as shown.

.In the horizontal portion of the angular standard C is formed a 'luh,b, through which is placed a shaft vor rod, I, having a crank, J, at its upper end.

A screw, d, passes from the lower end of thev shaft I through the spring H, and through the frame G.

On the lower end of the screw d, under or in a-recess on the under side of the frame G, is secured a washer, c, o r a nut and plug-washer, so as to lift the frame up with the screw.

The screw Z is flat on one side, and ou the same, above the spring H, is placed 'a washer, f, constructed to t the screw, which thus must turn with the screw, and have a free vertical movement therein.

Above this washer f is a nut, 71,011 the screw, for regulating the pressure of the" spring H.

On the inner side of the hub b, extending around one-halfits inner circumference, is an irregular groove, 7J, as shown in fig. 2, iu whiclf' moves a pin, t, fixed on the shaft I, so' that by turning the crankJ one-half of a revolution, the pin t is brought from the upper end yof the groove 7o to the lower end, which lowers the frame G and brings the upper roller E in contact with the lower roller I). 'By turning the crank J one-half of a' revolution in the opposite direction, the frame and roller are raised again.

The groove L at its lower end is projected in a horizontal plane, so that when the pin t rests therein the vertical movement of the shaft I is prevented, so that l no upwardpressure on the upper roller can move or turn the shaft. Ilhe upper end of the inclined groove is formed in a similar manner, so that when the shaft I is rotated and the upper roller raised to its highest point, it is locked in position, and the two rollers separated and supported in their open position to admit the introduction or removal of the fabric, andthe use of both hands. It is thus prevented from moving downward, except by the turning of the crank J.

These inclined planes m and a need not necessarily be arranged so as to form a groove betweenthem. They may, for instance, be arranged on opposite sides of the inner circumference of the hub b, in which case two pins'are necessary on the shaft I.

Then the upper roll is lowered into its place upon the lower roll, the4 pin t', moving down the groove, compresses the spring and enters the horizontal part of the groove at its lower end, which holds the shaft I from yielding to any upward pressure against the lower roll. The upper roller E is, however, allowed 'to yield suiliciently for all necessary purposes while luting, bythe action of the spring II.

Having thus described my invention,

IVhat I claim as new, and desire to secure-b57 Letters Patent, isn l. The right-angular roll-supporting frame G, pro

vided with a. slot through which the journal of theY k with a' stop nt each end for raising, lowering, and lower roller passes, and extended into the bed-plate locking thel upper' roll and compressing and holding bf the machine, all substantially as and for the pulthe spring H, all substantially as set forth. poseshexein set forth. In testimony that I claim the foregoing, I have '2.
